Dual-line systems Dual-line system are used on large machines or systems. They can lubricate points at a great distance. System structure These systems consist of two main lines supplied by a high-pressure pump at up to 400 bar with alternating cycles. While one line is under pressure the other one is in relief (by a change-over valve). Sometimes it is possible to installa End Line Switch. The Control unit is usually installed near the pump. Operating The system operates a two-phases alternating cycle. In the first cycle, lubricant is pumped in main line (A) moving inlet and discharge pistons...

Control unit DUAL-LINE Control unit 5N.TW..IN.CU TWIN-CU is a latest generation electrical device suitable for controlling double line lubrication systems in which you want to monitor and control all the functions. All the functions and program choices are made via the front panel controls of the PLC on the outside of the closing door. The electrical equipment operates by setting the machine pause or pulse time and a working time. The cycle consists of a pump start-up signal reception from the pressure switch line 1 or line 2 for inversion. If this signal is not received, an alarm is generated...
